OutdoorKing Repair Forum Forums Repairs and Maintenance Questions On Ride On Mowers Questions on Greenfield Ride On Mower Frames Greenfield Evolution 3

Hi guys.

Just got myself my first ride on. I think I got a bargain. a Greenfield Evolution 3 12.5 / 32 for $300. Blows a little smoke but am thinking about a new piston in the near future. is it possible just to do rings on this motor or should i do the piton as well?

any recommendations on oil? can I use something a little thicher then 30 weight to reduce smoke?

Just got a manual but want to make sure i have the corect model so here are some shots of my toy.

Previous owner has masked off the decals to give it a a coat of blue hammer tone. done a reasonable job. wouldn't mind doing this properly with new decals. Anyone know where I might be able to get some decals.






Great forum by the way.

Cheers Matt

most ov the Evo 3 that I have found have a bonnet scoop but mine only has the fluted vents.

Do you think this is the correct bonnet or is it from an older model.

Also can anyone give me an idea of the age of my mower?

Cheers

Hi Matt, welcome to Outdoorking.

The first thing we need is the information stamped on the cooling air cowl of that Briggs engine. It will be in three groups, labelled Model, Type, and Code, and will probably be on the vertical surface near the air cleaner. That will give us the engine's date of manufacture, and if it is the original engine, the date of manufacture of the mower will probably be just a few months later. In most cases, that same information will give us access to the engine's Illustrated Parts List, to find the part numbers for any replacement parts.

If the smoke it is blowing is blue, chances are you need to replace the piston rings. It would be unusual to need to replace the piston unless the engine has run a whole lot of hours and the rings have already been replaced at least once, or it has been seized up at some time (either by running out of oil, or having its cooling fins blocked up with grass, wasp nest, etc.)

The bonnet is correct, I own one that model and it has the same bonnet. Can.t confirm if its because they are early evo 3 or because they are lower optioned I don't know.

I have worked out the mower is an Evolution 3 Mk1 as it doesn't have a disc Handbrake. My brake has 4 notches in it so it will only lock in those 4 spots.

New problem.

I can not get the cutter belt off. Old one has stretched so I have a new one based on the Part number in the Greenfield parts manual.

I have removed the Idler pulley but the tensioner pulley seems to be stuck on this bolt. I cannot see another way of getting the belt off this pulley due to the guides holding it onto the pulley. do I need to get this pulley off this bolt or is there another way?

This youtube Video shows the pulley I am have trouble with and is this amount of sideways play normal for this pulley?



very Frustrating I am trying to avoid removing the deck to get this belt off so I can fit the new one.

Cheers

Matt

Anyone got any ideas here?

I normally take the main alloy pulley off. but I have access to a rattle gun so it only takes 2 secs.

Could be a painful way to do it if the decks still attached. If you do try just remember its left hand thread.
